TOPLINE:

Preoxygenation with a bag-valve-mask device did not reduce the risk for hypoxemia compared with preoxygenation with a facemask during emergency tracheal intubation in the emergency department (ED) or ICU.

METHODOLOGY:

Researchers conducted a post hoc secondary analysis involving 1156 patients (median age, 57 years) enrolled in two randomized trials, PREOXI and DEVICE, across nine EDs and 23 ICUs in the US.

Participants were categorized into two preoxygenation groups: 136 were preoxygenated using a bag-valve-mask device (without manual ventilation), and 1020 were preoxygenated using a non-rebreathing facemask (with or without a nasal cannula).

The primary outcome was the incidence of hypoxemia, defined as peripheral oxygen saturation < 85% between induction of anesthesia and 2
